Knowledge of the mechanical properties, i.e. strength, stiffness and deformation capacity, of cementitious materials at any arbitrary time is fundamental for operations such as removal of formwork, prestressing or cracking control. This paper presents a st ...
Structural elements combining Ultra-High Performance Fiber Reinforced Concretes (UHPFRC)and concrete offer a high potential in view of rehabilitation and modification of existing structures. The investigation of the time-dependent behavior of composite “UH ...
The aims of the preliminary study reported in this document were twofold. Firstly, within the context of the application of UHPFRC for the rehabilitation of reinforced concrete structures, to identify the phenomena that require further study with respect t ...
Ultra-High Performance Fibre-Reinforced Concretes (UHPFRC) have high mechanical strengths (fU,c > 150 MPa, fU,t > 6 MPa) and exhibit quasi-strain hardening in tension. Their very low permeability prevents the ingress of detrimental substances. In composite ...
Advanced Cementitious Materials such as HPFRCC are well adapted for durable repair and strengthening of concrete structures. Experimental and numerical investigations have been conducted to study the behavior of hybrid structural elements consisting of HPF ...
Rehabilitation projects aim to enhance durability and to ensure structural safety. Ultra-High Per-formance Fibre Reinforced Concretes (UHPFRC) may fulfil these requirements when used as conservation materials. The structural response of composite UHPFRC-c ...
